certain new and useful Improvement in Storage Batteries, of which the following is ed to rest on the bottom of the `jar 'is a a full, clear, and exact description.

This invention relates to a; storage battery i0 adapted particularly for radio work, and' h`as for its chief object the provision of a battery wherein the features of compact-v ntss and eiiiciency are obtained, and wherein leakage is minimized. Further'the iiirovide a battery. which can be produced inexpensively, and Awhich can be readily formed in small size, with the individual cells in round containers.

' The invention may be brieii '.suminarizech- 'as consisting in certain novel etails of construction, and combinations and arrangements of parts which will be described in 'the speciiications an'd pointed out in the appended claims.' In the accompanying sheets of drawings showing the preferred embodiment of the invention, Fig. 1 is a vertical sectional viewl through a cell embodying my invention; Fig. 2 is a perspective view sliowinfir 'the cover and battery elements of one cell removed from the jar or container; Fig. 3 is a transverse sectional view substantially along the line 3--3 of Fig. 1, lookin in the direction indicated by the arrows; ig.

for the plates and separator, but: holds the plates in and prevents theirspreading apart in the bottom of the cell. I When the unit shown in Fig. 2 is inserted 1n the Jar, the cover can be tightened by 90 screwing 1t in place,`the depending parts turning with the cover 'as it is tightened.

In order to provide a sealed construction, the lower yside of the cover is -grooved an'd receives a gasket 19. which is squeezed down 95 against the top edgeof the jar 10 when the 'cover is screwed intof place.

Each cell of my improved battery includes a ar`A orcontaincr 10 Vwhich is preferably cylindrical, and is formed of suitable insulating material, preferably glass. rIhe top of the'container is threaded to receive a threaded or screw cover 11, which is generally formedY of hard rubber. Inside the container lare lat positive andv negative ssl-plates designated 12 and 13.',"l`liese plates to the but-the bil-Alb'- bles are broken up before the gases reach" lthe upper end of the iral groove, and theacid runs gbacl into` t efcell.'
